Particle Area Radius | radius – Specifies the size of the particle area. This option is critical to the performance. The larger the Particle Area Radius, the longer it would take for the Particle Texture to render. In case you are using the Particle Texture as a Color Map in a Phoenix Particle Shader, always start with a very small Particle Area Radius - this way the particles would render with black edges. Keep increasing the Particle Area Radius until the black edges are no longer visible, and this way you would get the best render speed for your setup.
